From the Height of Excitement to Depths of Doubt in Just Three Weeks

The Wall Street Journal has an article about the questions arising as genetic testing becomes more readily accessible. With some 1,400 tests on the market, the article says, it's important for consumers to know which are backed by firm science and which represent wishful thinking on the part of the test developer. Also, the story says, "many experts note that most genetic tests are only loosely regulated, and aren't required to provide the type of rigorous scientific studies to back up their claims that the pharmaceutical industry must provide."

Earlier this week, a columnist for LiveScience challenged the validity of genetic testing and sparked a debate on the topic. Meredith Small, an anthropologist at Cornell University, calls genetic tests -- especially those designed to determine a person's ancestry -- "fraudulent" and "a scientific scam." That got the folks at the blog up in arms. A long post defending ancestry testing begins by saying that Small "has clearly shown, she doesn't fully understand DNA testing."
